Cadillac Allante: I have a 1992 Cadillac Allante with a difficult

Customer Question

I have a 1992 Cadillac Allante with a difficult R-12 substute refrigerant (MAXI FRIG) air conditioning problem - not a look it up in a Service Information Manual answer.
I am a 77 yr old DIY backyard fixer - you prob. know what a problem that can be.
Anyway I purchased all the parts, new compressor, new accumulator & new orifice tube. I realized the project was over my head - compressor is very difficult to replace. Sooooo
I had all the work done a a local Auto Repair Shop - everything seemed to work well. After about 10 min. I get the following error codes E52, E132, B446, B447 & B552 and the message A/C low on freon compressor off.
My Auto Repair Shop did over charge the A/C system - as they put 3 cans of MAXI-Frig and 1 can of oil in the system. They won't check anything because I provided everything, part, MAXI-FRI & oil.
Would you like to help me work through this problem with me - knowing that I am prob. part of the problems!!!!
